Added adjustable weight and different color options.
the mass of a single sphere is 1200 kg by default, which is a realistic value for its volume. The setting allows you to use weights from 100 kg to 4000 kg.

New colors (these are presets)

A very simple support offering a concrete sphere with a diameter of 1 meter with options of various shapes, including a horizontal row, a vertical row, a square and a stack (all pictured below).

Single (default) Horizontal Row Vertical Row Square Stack One sphere weighs 1200 kg, which makes it great for destroying things. It also rolls better than the stones presented in the game, which gives different possibilities for its use. The sphere does not break, although it may be slightly deformed. I can update it so that there is no deformation at all if people suggest this change.
